Abstract
A filter unit for a Raman microscope mounted with a dark-field objective lens unit includes a frame body, a plurality of UV-LED elements that is disposed around a window part of the frame body to emit UV light, and a long-pass filter that is supported to the frame body to cover the window part of the frame body and transmits a light having a wavelength longer than the wavelength of the UV light. The filter unit has a dark-field UV irradiation function, and is able to impart a fluorescence observation function to the Raman microscope.
